"We have fought, and will continue to fight, on behalf of our tribe in this case and will work to protect our financial resources," Baker said in the notice.

According to The Havre Daily News, which first reported on the story, BEH Gaming Ltd. of Florida won a court order in February in a breach of contract case. The firm had extended a loan to the tribe in connection with the expansion of the Northern Winz Hotel and Casino.

BEH filed the lawsuit in 2014, The Havre Daily News reported at the time. Then-chairman Ken St. Marks told the paper that the loan was apparently for $16 million and was supposed to be used to build a hotel and truck stop at the casino.

The tribe did add 10 hotel rooms to the facility and one gas pump, St. Marks told the paper, but he believes the loan was connected to corrupt activities among other tribal leaders on the reservation. About two dozen people were found guilty or pleaded guilty as part of a wide-ranging federal investigation.
